My optical drive is broken so I am wishing to install Windows 7 to use with Bootcamp, through a USB. I have downloaded the Windows 7 ISO from the Microsoft site and placed it on a USB drive. After having modified the script of the Plist of the Bootcamp Assistant, I was successful in creating a partition. The Late 2011 Macbook Pro rebooted to the black Windows screen prompting to boot from a device, but could not find the Windows 7 ISO and it's contents (including the Apple software drivers). The screen reads, "insert boot device and press any key to continue". The USB drive does not do the trick, and pressing any key on the keyboard does neither. Any recommendations? Update: I am running 10.11.1 and saw that Windows 7 is no longer supported...has anyone had luck with installing 7 on an up-to-date machine? The photo shows the contents of the USB drive that I am trying to boot from.
